MANUFACTURE OF DRESS-STAYS.

SIECI-FIGATION forming part Of Letters Patent No. 614,823, datedNovember 29, 1898.

Application filed April 2 9 1 89 8 T0 aZZ whom it may concern:

Be it known that I, GEORGE BEACOCK, of Brockville, in the Province ofOntario, in the Dominion of Canada, have invented certain new and usefulImprovements in the Manufacture of Dress-Stays, (for which I haveobtained a patent in Canada, No. 59,510, dated April 4, 1898,) of whichthe following is a specification.

My invention relates to the manufacture of dress-stays from rawhide, andthe object of the invention is to give to the material the requiredelasticity and spring to suit it to the requirements of use, and myinvention consists in the treatment of the rawhide as hereinafter setforth, whereby therawhide will be hardened and adapted to be cut intostrips and finished in imitation of whalebone.

The rawhide is prepared ..by first placing it on a table or fiatsurface, the hair side up, and dehaired by wetting with a solution ofsulfid of sodium, to remain wet for from six to ten hours. The solutionis made by dissolving the sulfid of sodium in water to be of thestrength from 15 to 18 Baum. Thehide is then washed and scraped andplaced in a solution of borax for about six hours to toughen the hideand clean out the sodium sulfid without destroying the gelatin in thehide. The solution is made by dissolving three pounds of borax in onehundred pounds of water or proportionately. The hide is then split tothe thinness required for the stays and the splits immersed in anydesired coloring-matter for appearance. The splits are then tacked tostretchers and dried, and when dry immersed in benzin or naphtha toremove natural odors and adapt the same to receive by impregn'ation awaterproofing liquid which is composed primarily of alcohol,gum-shellac, and rosin, with or without sulfur. The waterproofing liquidmay be applied to the hide or splits with a brush, or if in largequantity by dipping into the solution or liquid. The waterproofingcauses the hide to harden, and when Serial No. 679,186. (No model.)

cut into strips the strips become flexible like whalebone, of which thematerial is a good imitation. The strips of rawhide are passed betweenrollers having an abrasive surface to remove inequalities and finishedby passing them between buffing-rollers or through a buffing-machine andthen waxed to produce a polished surface.

I claim as my invention 1. The process of preparing rawhide for themanufacture of dress-stays, which consists in dehairing the hide byapplying sulfid of sodium dissolved in water, then cleaning the hide bywashing and scraping, then applying a solution of borax to toughen thehide and remove the sodium sulfid, then splitting the hide tov thethinness desired, and if preferred, staining the splits of a desiredcolor, then stretching the splits to dry, and when dried saturating themwith benzin or naph tha to remove natural and other odors, and applyinga waterproofing liquid to harden the hide splits, substantially as setforth.

2. The process of manufacturing dress-stays from rawhide, which consistsin dehairing the hide by applying a solution of sulfid of sodium andcleaning the same by washing and scraping, then applying a solution ofborax to toughen the hide and remove the sodium sulfid, then splittingthe hide to the thinness desired, staining the splits if preferred andstretching the splits to dry, and when dried saturating them with benzinor naphtha to remove natural odors, then applying a waterproofing liquidto harden the hide splits or material, then cutting the same intostrips,

and passing the strips between rollers having an abrasive surface andfinally buffing and waxing the strips to give a finished appear ance, asset forth.

GEORGE BEACOCK.
